Maintain Clean and Clear Water with UV Sterilizers and Ultraviolet Sterilizers

Proper aquarium maintenance entails dedication by many aquarists and marine hobbyists. From changing out and conditioning the water in your aquarium as well as regularly replacing your filters to gently cleaning your aquarium walls, substrate and other tank décor, maintaining a clean and healthy environment for your aquatic life necessitates various procedures and tools. UV sterilizers help in tank maintenance by killing microscopic organisms, such as various types of parasites, algae and bacteria. In killing aquarium algae and preventing it from blooming, Ultraviolet sterilizers inhibit the formation of green and murky water conditions, helping to keep your water clean and clear. As some aquariums necessitate a great amount of lighting, they are more susceptible to the spread of various types of microorganisms. UV sterilizers can be quite beneficial in eradicating any free-floating microorganisms as well as helping in the prevention of fish disease. Ultraviolet sterilizers have even been known to help prevent the spread of Ichthyophthirius multifiliis, commonly referred to as "Ich", by killing the disease-causing parasitic protozoan during its juvenile stage. Along with an adequate filtration system and routine water changes, a UV sterilizer can help you maintain healthy water conditions for your fish, coral and other magnificent aquatic life, allowing them to thrive.

Beneficial to both freshwater and saltwater aquariums, UV sterilizers are frequently utilized in outdoor ponds to boost water clarity and cleanliness, as well as help to support the overall health of your pond fish. To ensure that the ultraviolet bulb, ballast and electrical connection are kept dry, there is the Lifegard Aquatics Raintight Box for Ultraviolet Sterilizers that is both durable and easy to use. In addition, there is a large assortment of replacement bulbs available, that range in shape, size and output capacity in order to accommodate the unique requirements of various types of UV sterilizers within your aquariums and ponds.

Specifically designed for use with the Oceanic BioCube Aquarium are Oceanic BioCube Mini Ultraviolet Sterilizers, which conveniently attach directly to the BioCube pump making for easy set-up and use. To achieve optimal results using your UV sterilizer, it's important to control the rate at which your aquarium water flows through the sterilizer in accordance with your sterilizer's recommendations. Equip your aquarium or pond today with a UV sterilizer and help to improve water clarity as well as decrease the chances of disease among your fish and aquatic life.
